5. Claims, (01. 1 -47) position on walls, trees, and buildings, from astanding position on the ground without the necessity of employing aladder or other means upon which he may stand.

Another object of this invention is the produc tion of a simpleandefiicient sign posting hammer, which is provided with means for engaginga sign and'facilitating the elevation of the sign to the desiredposition high upon'a suitable support, and then releasing'a springactuated hammer for the purpose of driving a supporting tack, nail, orother fastening means, I

A further object of this invention is the production of a simple andefiicient hammer particularly adapted for use in posting signs, whichconsists of a minimum number of'parts, is efiicient in operation, and isinexpensive in maintenance.

'With these and other objects in view, this invention consists incertain novel constructions, combinations andflarrangements of partsaswill be hereinafter fully described and claimed.

Figure 5 is a section taken on line ure 4;and r V Figure 6 is a sectiontakenon line 6-6 of Figure 5. V i i i By referring to the drawin it willbe seen that 1 designates the elongated shank of a hammer which may beofmaterial length, preferably anywhere from 4 to 8 feet long, thisshankconstitut- 'ing the stock of the hammer. The shank or stock 1 isprovided with a longitudinally extending channel 2 upon its frontface'within whichlongitudinally extending channel 2 is slidably mountedthe trigger rod 3, the trigger rod being guided through. the guide plate4, 35511013711 clearly in .Figure 2; A coil spring 5 is'carried by thetrigger rod '3, and is adaptedtourge the trigger rod 3 in adirectiontoward the outer end of the hammer. The inner end of the trigger rod 3is provided with an aperturefi through. which extends the projectingfinger 7 of the pivoted tri er 8. An actuating knob 9 is carried bythelower end of the trigger 8, -as. shown clearly in Figure 1,

5-5 of Figthe knob 9 beingconstructed in" any suitable or desired mannerand being adapted to be depressed for pulling downwardly upon thetrigger rod 3 'and facilitating the releasing of the trigger rod 3 fromthe hammer arm hereinafter described.

The knob 9 is adapted to work-within the lower end of the longitudinallyextended channel 2 of the shank or stock 1.

Mounted in any suitable or desired manner near the upper end of thestock or shank 1 is a lock casing 10, having an outer plate 11 and aninner plate 12, these plates Hand 12 being properly spaced by means ofthe transverse spacing plates 13 and 14. The plates 11 andll2 are heldtogether by suitable connecting screws 15. -The outer plate 11 may alsobe secured to'the outer face of the stock and preferablyflush therewithby means of suitable fastening screws 16;

Pivotally mounted between the plates 11 and 12 is a hammer arm 17 whichis carried upon a pintle member 18, the hammer arm 17 being mounted uponthe rectangular" shank 19 of the I pintle member 18, and awash'eror-other suitable spacing means 20 being also mounted upon therectangular shank 19intermediate the plate 12 and the hammer arm 17,- asshown in Figure 5. Aspiral coil spring 21 is secured at one end to thepintle member '18, the opposite end of the spiral .coil'spring 21beinganchored upon a suit-' able pin 22, as shown in Figure 4; The hammer arm17 is providedwith a rectangular aperture 23 for fitting over therectangular shank l9; in

order that the arm 17' may be-anchored or keyed upon the rectangularshank 19.

The hammer arm 17 is provided upon one edge thereof with a trigger rodreceiving" notch 24 for the purpose of receiving the inner end of thetrigger rod 3, and holding theihammer arm-1'7 'ina cocked position. Asuitable eye 25 is also carried by'the hammer arm 17 near its outer endnected to this eye 25, if desired, :for the purpose offacilitating, the,operation of the,

hammer arm 17;; The hammer head 27, preferably of a magnetic type, iscarried by the outer end of the hammer arm l'l and the outer end of theshank or stock 1 is provided with; a hammer head receiving aperture 23into which the hammer head is adapted to move for the purpose of drivinga'tackr A tack 29 may be secured to the outer end of the hammer head,the hammer head 2'7 being magnetized, and as soon as the trigger rod 3is released from the hammer arm 17, the coil spring .21 willcause'the'hammer head 27 to be driven into theaperture 28 as shown indotted lines in'Figure 1, for the purpose of I driving the tack29 into asupport,

. me ng er swqk 11s provided with: an enlarged head 33 near its upperend and upon the inner face of the head 33 are secured a plurality ofspring clips 34 for the purpose of fitting over the upper edge of asuitable sign 35 and efficiently supporting the sign in position forreceiving the tack 29 as it is driven. Upon either side of the head 33,as shown in Figure 3, are mounted pointed wire spurs 36 for the purposeof facilitating the straightening out of fabric signs, or the moving ofa sign to a proper position after the first nail or tack has beendriven. These spurs 36 preferably diverge outwardly at their terminals,as shown clearly in Figures 2 and 3, in order to facilitate the grippingof a sign for moving the sign to a proper position, such for instance asstraightening the sign after the first tack has been driven.

t From the foregoing description, it will be seen that a very simple andefficient sign posting hammer has been provided of an elongated type,whereby an operator may stand on the ground level and reach up to a highposition for the purposeof tacking a sign to a support at a sufficientheight to prevent the sign from being torn down or otherwise injured bymischievous parties. The construction of the hammer will permit the signto be posted without the necessity of the operator climbing upon aladder or other elevating support.

In operation, it will be seen that the sign 35 is placed under the clips34 and the hammer is raised to the desired point where the sign is to beposted and merely by pressing the knob 9, the rod 3 will be pulleddownwardly against the pressure of the spring 5, thereby releasing theupper end of the rod 3 from the notch 24 of the arm 17 by causing theupper end of the rod to slide downwardly through the plate 14. As soonas the arm 17 is released, the coil spring 21 will cause the arm 17 torapidly swing upon its pivot ,pintle 18, and this will drive the hammerhead 27 through the aperture28 and cause the tack 29 to... beinsertedthrough the upper edge of the sign 35 and into a supportwhereupon the ham- ,mer may be raised slightly for withdrawing the clips34 from the edge of the sign and the sign may be gripped by the spurs 36for straightening after a further tack has been secured to the hammerhead 2'7 and other tacks inserted through the sign and into the support.I

From the foregoing description, it will be seen that a very, simple andefficient means'has been provided inthe nature of a sign posting hammerwhich will be efficient in operation, cheap in construction, and whichwill not be likely to get out "of order.

Furthermore, the provision of a simple structure as provided, willenable a sign poster to properly place a sign at a proper height out "ofreach of unauthorized parties and will also permit the sign poster toefficiently secure or attach the sign to a support without the necessityswinging said hammer arm from a cocked to a driving position, saidhammer arm being provided with a notch formed therein for receiving theupper end of said trigger rod for permitting the holding of said hammerarm in a cooked position, a hammer head adapted to carry a tack carriedby the outer end of said hammer arm, said shank being provided with ahammer head receiving opening near the outer end thereof, and signsupporting means carried upon the upper edge of said shank forsupporting a sign in the path of movement of said hammer head.
